Analysis Corridor Area for the Tiger Conservation in the

Dangku Landscape, Sumatra, Indonesia

(SCGIS 2011)

Background

1. We have 8 species of tiger in the world .

But 3 of them extinct already

(Caspian/Persian tiger – extinct 1970’s)

Armur/Siberian tiger: 320 kg (270–330 cm )

Bengal tiger: 300 kg ( 300 cm)

Indochinese tiger: 200 kg (255-2.85 cm)

Southchinese tiger: 150 kg (260 cm)Southchinese tiger: 150 kg (260 cm)

Sumatran Tiger: 120 kg (240 cm)

2. Indonesia has 3 species of tiger:

P.t. balica – extinct 1940’s,

P.t. sondaica – extinct 1980’s,

P.t. sumatrae ??

1. Since 1997’s there was economic problem

and cause land use conversion and loss

some endanger species include their habitat

and their prey

2. Population of P.t. sumatrae decreasing

about 70 % about 3 decade (national

documentation)

3. Threat: 3. Threat:

- Degradation/deforestation forest (fragmented)

- Hunting

- Trafficking (Symbology, medicine, magic etc)

1. There are many TCLs (Tiger Conservation Landscape) and its was priorities into the big national

park by the government and consolidate with the GTI (Global Tiger Initiative), but there are many

small “island” as tiger habitat still need to conserve (protect) and monitor

2. Dangku’s landscape around 3,200 km2 within protected forest, plantations & community inside

Goals

1. Biodiversity monitoring for the tiger and their prey

2. Make tiger corridor area inter-habitat (Protection forest &

plantations)

3. Using tiger as flagship program for complex conservation 3. Using tiger as flagship program for complex conservation

in the landscape scale with participative collaboration

Method

1. Pre-analysis the landscape area

matching with the national tiger

zone survey

2. Field survey using:

- Transect

- Camera trap

- Groundtruthing (Image analysis)- Groundtruthing (Image analysis)

3. Database tabulation

4. Maps tabulation process

5. Imagery analysis

6. GIS analysis for corridor scenario

National Tiger Protocol

Survey Grids

• @ 289 km2 (17 x 17 km)

• Require ≥ 10% tiger habitat

Random Cells

• @ 18.06 km2 (4.25 x 4.25 km)

• Require ≥ 30% tiger habitat

Data Collection

• 1 km replicate (= 1 occasion)

• 100m data recording

• 1 rand. Cell / team to go

• ≥ 4 km & all possible habitat

Analysis

presence/absence surveys with detection/non-

detection survey (MacKenzie et al. 2002, 2006).

Zone Area

There will be 3 zones area:

1. Core Area

2. Corridor area

3. Buffer Area

CORE AREA: ± 34%1. SM Dangku (Wildlife reserve)1. SM Dangku (Wildlife reserve)

2. PT REKI (Restoration Forest)

3. 3 Protected Forest (HL Dangku-2, HL

Kedempo, HL Sungai Jernih)

It’s should be 40% area can be used for the

conservation

CORRIDOR AREA:

Forest Concession (Plantation): ± 48 %

1. PT. Sentosa Bahagia Bersama (SBB)

2. PT. Bumi Persada Permai (BPP)

3. PT. Pakerin

4. PT. Wahana Agro Mulia (WAM)

Zone Area

20/07/2011Slide 19

4. PT. Wahana Agro Mulia (WAM)

� At least 10% from the area should be

managed as conservation area

(Government regulation)

� HCV-F area in the oil-palm plantation

� Artificial corridor can be managed at

Concession

SUPPORTING AREA for economic & social

purpose (rest of the 38% production forest

& community land)

Corridor Scenario

-There are small “island” area

could be used for the

connecting “corridor” between

the big “island” habitat (REKI &

SM Dangku)

- That needs negotiation

process with the forest process with the forest

concession companies & local

communities for the corridor

concept implementation (using

the map as “language tool”)

- It need more detail information

about tiger home range & the

number of tiger in the Dangku’s
